We process 80 GB for you in January.The effective rate per GB would not increase to *$187.50, instead, You would retain the effective rate of only *$150 per GB. The unused allowance of 20 GB would then be applied to the next month (February), which would increase from 100 GB to 120 GB total.

Scenario 2:

We process 120 GB for you in January.The effective rate for the allowance (100 GB) remains at *$150/GB and the overage (20 GB) would be billed at our standard rate of *$250 per GB. However, You would start the next month (February) with the usual allowance of 100 GB.

Advantage of Rollover eGigsSM vs. commonly offered Flat Rate pricing:

You know that data volume fluctuates from one month to the next, so why let the unused GB allowance go to waste? Since You paid for it, You should receive the product you paid for.

Is there a catch? No. You have control over your charges and volume as well as the associated cost to Your clients.

What happens at the end of the contract? Unused allowance is simply re-credited to You.
